What are the causes of cracking of nickel alloy coating? The causes of cracks in the coating are: (1) cracks due to internal defects of the base metal of the copper plate expand outward, causing cracks in the plating layer. (2) Due to the metallographic structure of the alloy plating layer, impurities exist in the…
What effect does the internal water jacket have on cooling and heat transfer？The water jacket in the diversion of the high-efficiency crystallizer adopts the integral water-filling inner water sleeve, which overcomes the problem of low processing precision and uneven water seam in the original welding water jacket, ensuring uniformity of the water gap between the…
The difference of composite coating and Cr coating: The base layer of the composite coating has good bonding strength with the base material, and the internal stress of the coating layer is small, but the composite layer is easy to fall off, and the service life is limited by the thickness of the composite layer;…
How to overcome the deformation of the upper part of the copper mould tube during the drawing process? High-efficiency flanging crystallizer: It adopts the upper end of the crystal copper tube to suspend and the lower end free structure, which is beneficial to suppress the deformation direction caused by the thermal expansion and contraction of…
What is the requirement of high efficiency continuous casting for the copper mould tube taper ? At present, the taper values of high-efficiency crystallizer copper tubes used by various steel mills are generally 0.6-0.9. When the low-carbon steel and low-alloy steel are pulled, the taper value is taken as the middle and lower limit, and…
(1) Prevent secondary oxidation of molten steel The tundish flows into the copper mould tube, and the metal surface in the copper mould tube is continuously renewed due to the impact of the injection. When the mold flux is added to the molten steel surface in the copper mould tube, the liquid slag layer, the…
Continuous casting mould powder-Ultra-low carbon steel billet As we known,continuous casting process is one of the main parts to increase the carbon content of ultra-low carbon steel.the greatest extent to reduce the carbon content of the mould flux,which is extremely beneficial to avoid increase carbon content on the liquid steel. Continuous casting mould powder-Low carbon…
How to use the mold copper plate, mold copper tube and coating of different casting machines?For billet continuous casting, there are many copper mould tubes with TP2. The billet is generally gradually made of chromium zirconium copper copper mould tube, especially the copper mould tube with unequal square billet crystal mold is preferably chrome zirconium…
What are the advantages of the concave-convex crystallizer copper tube and the diamond-type crystallizer copper tube?At present, continuous casting is developing towards high speed, high operating rate and high quality. The main way to increase the pulling speed is to improve the shape of the inner cavity of the copper tube of the mold, and…
Copper mould tube The coating drop off,corroded etc. There are two kinds of coating drop off,one is the general crack shedding,mainly because the plating layer is caused by the poor bonding force,which is because the pre-plating treatment is improper,and the other is in the continuous casting process,the pulling speed,the protective slag,cooling water,steel and other factors…
